Frequency Converter

Frequency converter use rectifiers to convert ac power line electricity into direct current. Then inductor-capacitor filters smooth its waveforms and pulse-width-modulation inverters turn it into shaped ac power with a frequency of 2 to 12 Hz. This output is used to drive motors for constant torque or (with the help of encoders) to control motor speed. frequency converters are proliferating, as they save substantial amounts of energy during motor operation âÛ" an objective of increasing importance. Some frequency converters have built-in ac and dc brake functions to help transform kinetic energy from the application into braking power.

Variable Speed Drives

Variable speed drives are ONLY for 3 phase motors, any method to speed control an induction motor. Variable speed drive with ONLY single phase input can drive capacitor start/run single phase motors. Variable speed drive operating from single phase have output voltage on each phase equal to input voltage. Higher capacity single phase motors with separate high torque/high current starting winding operated by centrifugal switch can not be used with variable speed drive. However a triac speed controller may work, as this could duty cycle the AC sine wave form. Try an off the shelf light dimmer and see if this can control the desired speed range of the fans. If this works, then some circuit research/lab work could produce a circuit that takes 0...
